I have a 2007 BMW 328i with automatic transmission and 92,000 miles. Within a mile of my home, I have to go over a set of railroad tracks and the incline leading to the tracks is rather steep. In fact, there is a sign warning travel trailers not to go over the tracks because they will get stuck with their wheels off the ground. Anyway, every time I take my BMW across the tracks, my transmission slips. After I go over, it is business as usual. Has anyone ever heard of this issue?
